Injured cat: what to do
Rescue guide · Last reviewed
Short answer
Cats hide illness better than almost any animal people encounter. A cat that is visibly unwell in the open has usually been unwell for days, and a cat that sits still and lets a stranger handle it is not being friendly — it is too weak to leave. That single observation is the most useful piece of triage on this page.
The handling advice is also genuinely different from a dog's. A cat is small enough to contain, which makes containment the right goal, and it has five weapons and the flexibility to use all of them at once — which is why the towel goes over the head first.
How to contain and help an injured cat
You will need: A thick towel or blanket · A cat carrier, or a sturdy cardboard box with air holes and a lid · A quiet, dark room away from dogs and children
- 1
Watch it for a minute before you approach
Note whether it can walk, whether it is dragging its back legs, where the bleeding is, whether it is breathing with its mouth open, and whether it can lift its head. A cat breathing through an open mouth is an emergency — cats do not pant like dogs, so open-mouth breathing means real respiratory distress.
- 2
Approach low, slow and side-on
Crouch rather than looming over it, come from the side rather than head-on, and let it see your hand before it feels it. Do not corner a cat in a space with no way out — a cornered cat will go through you rather than past you.
- 3
Drape a thick towel over the whole cat
Cover the entire cat, head included. Covering the eyes stops most of the fight instantly, the towel gives you a layer between you and teeth and claws, and it stops the cat seeing what happens next. Use a thick towel, not a thin cloth, and not a plastic sack.
- 4
Lift the whole bundle, supporting the body
Scoop the towel-wrapped cat up supporting its chest and hindquarters together, keeping the body straight, and hold it against your own body. Never lift a cat by the scruff, by a leg, or by the tail. If it struggles violently, put the whole bundle down gently rather than tightening your grip.
- 5
Put it straight into a carrier or a closed box
A cat carrier is ideal. Otherwise use a sturdy cardboard box with air holes punched from the inside outward and a lid that closes properly — cats escape from anything open, and a loose frightened cat indoors is very hard to recover. Line it with the towel.
- 6
Keep it dark, quiet and away from dogs
Put the closed carrier somewhere dark and quiet at normal room temperature, away from dogs, children, and household noise. Do not keep opening it to check. The single kindest thing you can do for a shocked cat is leave it alone in the dark.
- 7
Give no food, water or medicine
No milk, no food, no water poured into the mouth, and no medicine of any kind. Cow's milk gives most adult cats diarrhoea they cannot afford, and a cat that may need anaesthesia must have an empty stomach. Paracetamol is lethal to cats even in a single small dose.

Call a rescuer or a vet
Ring your area's animal rescue contact, or take the carrier straight to a vet. Say what you saw, how long the cat has been like this if you know, and whether it is breathing with its mouth open — that last detail moves a case to the front of the queue.
Do
- Use a thick towel over the head first. It is safer for you and calmer for the cat than any grip.
- Note the exact spot you found it. Street cats have territories and are often returned to them.
- Say on the phone if it is breathing with its mouth open, or if a dog was involved.
- Keep the carrier covered with a cloth in the car — a cat that cannot see stays much calmer.
- Wash any scratch or bite with soap under running water and see a doctor the same day.
Do not
- Never give paracetamol. A single tablet can kill a cat. Do not give any human medicine.
- Do not give cow's milk. It is the most common well-meant mistake made with street cats.
- Do not lift a cat by the scruff, a leg or the tail.
- Do not use a wire cage or an open basket — a frightened cat will get out.
- Do not try to clean, flush or dress a wound, or pull out anything embedded in it.
- Do not put an injured cat in with a dog, even a gentle one.
Signs a cat needs a vet today, not tomorrow
- Breathing with its mouth open, or breathing fast with visible effort.
- Straining repeatedly in the litter or on the ground without passing urine — in a male cat this is a blocked bladder and is fatal within a day or two.
- Pale, white or yellow gums, or a yellow tinge to the eyes.
- Dragging the back legs, or walking on the hocks rather than the paws.
- A wound that is swollen, hot and firm — cat wounds abscess fast.
- Not eating or drinking at all for more than a day, or hiding in a tight dark space and refusing to come out.
Why a friendly street cat is a warning sign
Healthy street cats keep their distance from strangers. It is how they stay alive. So the behaviour people read as affectionate — sitting still, letting itself be stroked, not moving away when approached — is in a street cat usually a sign of weakness, fever, dehydration or pain.
This is the opposite of the rule for birds, where a bird that lets you approach is the sign to act, and it catches people out. If a street cat that has never let you near it suddenly does, treat it as an illness until a vet says otherwise.
If the cat has hidden somewhere you cannot reach
Injured cats go into engine bays, drain pipes, gaps under staircases and the undersides of parked cars. Do not drag one out by whatever part you can reach — that is how spines and legs get damaged, and how people get bitten deeply.
Tell the rescue team exactly where it is instead. They have graspers, nets and the experience to get a cat out of a confined space without a struggle, and a cat that has not been fought with is much easier to treat when it arrives at the clinic.

I found an injured cat. What should I do?
Drape a thick towel over the whole cat including its head, lift the bundle supporting its chest and hindquarters, and put it into a carrier or a closed ventilated box lined with the towel. Keep it dark, quiet and away from dogs. Give no food, water or medicine, and call a rescuer or vet.
Can I give a cat paracetamol for pain?
No. Paracetamol is lethal to cats — a single tablet can cause fatal liver damage and destroy the blood's ability to carry oxygen. Cats lack the enzyme needed to process it. Never give a cat any human medicine, including ibuprofen, aspirin or anything applied to the skin.
Should I give an injured or stray cat milk?
No. Most adult cats cannot digest the lactose in cow's milk and it causes diarrhoea, which a sick or injured cat cannot afford. Plain water in a shallow bowl within reach is fine for a cat that is alert and drinking by itself. An injured cat that may need anaesthesia should have nothing at all.
A street cat is suddenly letting me stroke it. Is that a good sign?
Usually the opposite. Healthy street cats keep their distance from people, so a cat that abruptly becomes approachable and sits still is often weak, feverish, dehydrated or in pain. If a cat that never let you near it suddenly does, have it checked by a vet.
How do I pick up a cat that is hurt and might scratch?
Do not use your hands directly. Drape a thick towel over the entire cat, head first, then lift the whole bundle while supporting the chest and hindquarters. The towel covers its eyes, which calms it, and puts a protective layer between you and its teeth and claws. If it fights hard, set the bundle down rather than gripping tighter.
A cat is straining to urinate and cannot. Is that an emergency?
Yes, particularly in a male cat. Repeated straining with nothing passed usually means a blocked urinary tract, which is fatal within a day or two and is one of the few genuine same-hour emergencies in cats. Get it to a vet immediately rather than waiting for a rescue volunteer.
The cat has run under a car and I cannot reach it. What now?
Do not drag it out by a leg or the tail. Note exactly where it is, keep people and dogs away so it does not move further, and call a rescue team — they have graspers and nets and can get a cat out of a confined space without a struggle or a bite.
This guide covers containment and transport first aid only — the same advice rescue groups give over the phone. It is not veterinary treatment and does not replace a vet. Any injured, sick or orphaned wild animal should be handed to a registered rescue group or a veterinarian as soon as possible.
